int OpenXcom::Zoom::_zoomSurfaceY ( SDL_Surface *  src, SDL_Surface *  dst, int  flipx, int  flipy  )

static

Copy src to dst, resizing as needed. Please don't use flipx or flipy as the optimized functions ignore these parameters.

Internal 8-bit Zoomer without smoothing.

Source code originally from SDL_gfx (LGPL) with permission by author.

Zooms 8bit palette/Y 'src' surface to 'dst' surface. Assumes src and dst surfaces are of 8-bit depth. Assumes dst surface was allocated with the correct dimensions.

Parameters

src	The surface to zoom (input).
dst	The zoomed surface (output).
flipx	Flag indicating if the image should be horizontally flipped.
flipy	Flag indicating if the image should be vertically flipped.

Returns

0 for success or -1 for error.

void OpenXcom::Zoom::flipWithZoom ( SDL_Surface *  src, SDL_Surface *  dst, int  topBlackBand, int  bottomBlackBand, int  leftBlackBand, int  rightBlackBand, OpenGL *  glOut  )

static

Flip screen given src and dst; might use software or OpenGL.

Wrapper around various software and OpenGL screen buffer pushing functions which zoom.

Basically called just from Screen::flip()

Parameters

src	The surface to zoom (input).
dst	The zoomed surface (output).
topBlackBand	Size of top black band in pixels (letterboxing).
bottomBlackBand	Size of bottom black band in pixels (letterboxing).
leftBlackBand	Size of left black band in pixels (letterboxing).
rightBlackBand	Size of right black band in pixels (letterboxing).
glOut	OpenGL output.
